The Science of Biology

A general style of investigation, not a rigid step-by-step process. Inferring and Hypothesizing, Designing controlled experiments, Collecting Data, Analyzing Conclusions, Exploration and discovery, community analysis and feedback.

To design an experiment you have to make observations, a hypothesis, and then you must perform a procedure with an experimental group and a control group.

Controlled variables are the variables that do not change throughout the procedure. The Manipulated variable is the variable that changes (there can be a manipulated testing group and a control group). Responding variable is how the organism tested responds to the manipulated variable.

Theory applies to a well tested explanation that unifies a broad range of observations, no theory is considered absolute truth, as new evidence is uncovered a theory may be revised or replaced by a more useful explanation.

Living things are made up of cells They are based on a universal genetic code called DNA-organisms store the information they need to live, grow, and reproduce They Reproduce. There Are two categories for reproduction: In sexual reproduction, cells from two different parents unite to form the first cell of the new organisms. Offspring are not genetically identical to parent cells. In Assexual reproduction a single parent produces offspring that are genetically identical to itself. They grow and develop They respond to the environment. A stimulus is a single to which an organism’s response They maintain an internal balance. Conditions outside may change, but conditions inside the organisms remain constant, homeostasis, Taken as a group, living things change over time Living things obtain materials and use energy. Organisms can break down and build up materials- metabolism.,
